Where Each One Wins

The recorded data shows a complete sweep: the Intel Core Ultra 5 245HX wins all 17 head-to-head benchmark comparisons. The Core i7-14701TE does not claim a single victory in any tested workload. The closest margin appears in PassMark integer math, where the Ultra 5 leads by 28.6%, while the largest gap is in data encryption, where the Ultra 5 leads by 61.0%.

For single-threaded tasks, the Ultra 5 245HX demonstrates a decisive edge. In Cinebench R23 single-core, it scores 4568 versus 2405 for the i7-14701TE, a 47.4% advantage. The PassMark single-thread result is 4481 versus 2637, a 41.2% lead. This translates directly to responsiveness in lightly threaded applications such as spreadsheet recalculations, web browsing, and legacy software.

Multi-threaded workloads show an even larger separation. The Ultra 5 245HX scores 32358 in Cinebench R23 multi-core, nearly double the i7-14701TE's 17035. PassMark multithread results follow the same pattern: 38069 versus 20042, again a 47.4% delta. The 14 physical cores of the Ultra 5 outperform the 8 cores with 16 threads of the i7-14701TE across every parallel benchmark.

Specialized compute tasks reveal the Ultra 5's strengths in encryption and instruction-heavy operations. Data encryption scores 30022 versus 11699, a 61.0% gap. Extended instructions show 31212 versus 14354, a 54.0% lead. Prime number finding scores 359 versus 143, a 60.2% difference. These results indicate the Arrow Lake architecture delivers substantially higher throughput in cryptography, SIMD, and mathematical workloads.

The i7-14701TE remains competitive only in terms of boost clock and cache size. Its 5.20 GHz peak and 33 MB L3 do not translate to benchmark wins, but they position it as a capable desktop processor for users who prioritize ECC support and DDR4 compatibility. The data, however, leaves no ambiguity about which chip delivers higher performance in every measured category.
